KA - 2 Behaviourism Flashcards
behaviourism assumptions
- human behaviour is learnt (stimulus generates a response)
- behaviour should be studied objectively
- rejects introspection as it is too vague
- aim for high control and objectivity
- all humans born as ‘tabula rasa’
- nothing is innate
what is clASSical conditioning
learning through ASSociation - 2 stimuli together drive a response
key studies
Pavlov’s dogs, little albert rat
how did Pavlov’s dogs use classical conditioning models
BEFORE: food(UCS) —> salivation(UCR)
DURING: bell(NS) + food(UCS) —> salivation(UCR)
AFTER: bell(CS) —> salivation(CR)
what is operant conditioning
learning through rewards and consequences
what will rewards and consequences do
rewards will strengthen behaviour
consequences will weakness behaviour
what is positive reinforcement
add a positive stimulus to encourage the good behaviour again
what is negative reinforcement
subtraction of a negative stimulus to strengthen good behaviour
key study of operant conditioning
Skinner’s box:
PR - when the rat presses the lever it gets a food pellet
NR - electrify floor of box so pressing the lever turns it off
evaluation of Skinner’s box
pros:
- scientific as the variables are highly controlled, repeatable
cons:
- unethical
- animals are not humans so not generalisable
- lacks ecological validity
pros of the behaviourist approach
- It is scientific so it is high control of variables -> can establish cause and effect relationships. High control also allows for replication -> check for consistency of findings and reliability
- Practical application -> token economy based of operant conditioning -> system of desirable behaviours so get token for good behaviour and can trade in tokens for something you want. Can be used in prisons, schools, parental gain -> real world behaviour modification
cons of the behaviourist approach
- Only look at observable behaviours -> ignore cognition -> leads to incomplete understanding/explanation and ignores individual difference in thoughts
- Scientific so lacks ecological validity as it is in a control environment -> lab setting, hoping for fewer extraneous variables so not true to everyday life -> lacks accuracy to the real world so lacks validity
- It is unethical -> unnecessary pain to animals -> cannot generalise as human’s brains are more complex and developed.
- However, token economy is short term. When token is removed the good behaviour stops. Unethical? -> strips away rights in prisons to earn them back -> can be dehumanising.
